Saw this bug that was breaking these examples while I'm poking around and learning things so I figured I'd update it for you as well, THREE.OrbitControls: The second parameter "domElement" is now mandatory.
I also noticed the default template that is created when using threejs is the wireframed sphere, but I was going the frontend masters course so that's what led me to come and find the square example.
